“The ghost in the machine”*… 


Pity (detail), by William Blake, c. 1795

How is it that mind and body manage to interact and affect each other if they are such different things? This question was pressed on Descartes in the spring of 1643 by a young woman of twenty-four, Elisabeth von der Pfalz, also known as Princess Elisabeth of Bohemia. When others raised such difficulties, Descartes tended to brush them aside. But he listened to the princess…

Anthony Gottlieb tells the remarkable story of the correspondence between René Descartes and Princess Elisabeth of Bohemia—a debate about mind, soul, and immortality: “The Ghost and the Princess.”

* Gilbert Ryle (The Concept of Mind, in part a critique of Descartes’ mind-body dualism)


As we try to get it together, we might that it was on this date in 1404 that King Henry IV signed into law the Act Against Multiplication– which forbade alchemists to use their knowledge to create precious metals… and effectively, thus, outlawed chemistry in England.  Since the time of Roger Bacon, alchemy had fascinated many in England.  The Act of Multipliers was passed by the Parliament, declaring the use of transmutation to “multiply” gold and silver to be felony, as a result of concern that an alchemist might succeed in his project– and thus bring ruin upon the state by debasing the national currency and/or furnishing boundless wealth to a designing tyrant, who would use it to enslave the country.  The Act was in force until 1689, when Robert Boyle and other members of the vanguard of the scientific revolution lobbied for its repeal.
